In Constructed, it depends on how much Scion tokens or other expendable creatures are used for the Abomination to be good. There are already cards in Standard, however, that synergize well with his ability, including Liliana, Heretical Healer, Grim Haruspex, and even Bloodsoaked Champion - who can serve as a repeatable sacrifice outlet. If something like Bloodghast - which comes back from the yard each time a land comes down - were in Standard, this would probably be a staple. Unfortunately, this Abomination is a bit too fragile for Modern with only 3 toughness (gets Lightning Bolted all day).
The best application for Smothering Abomination is definitely in Commander, where sacrifice outlets are plentiful, not only in Mono-Black decks, but in any deck that benefits from sacrificing creatures. The list of commanders this works well alongside is too long to list, and the card draw this guy can create is pretty sick in the format.
Still, in the right Standard deck, a one-of or two-of of Smothering Abomination could happen. Card draw is always powerful and a flyer that can hit for 4 is always welcome.
